He probably get mad because when he bought Minecraft on the Nintendo switch he thought he was getting a java edition on the switch, but then he find out that you can only get java on the PC, and that bedrock edition is the Minecraft on the Nintendo switch. He get so mad that he want me to emulate java in switch which I Don’t know how to.
I suspect that the development of minecraft is slowed down considerably by trying to make it work cross platform. It’s one thing to focus on Java updates but also bedrock and making sure it works on mobile and different devices and hardware. Every time you make a change or addition you have to make sure it won’t break on these various platforms. I’m a bit wary of Bedrock as concerned that Microsoft is going to push towards a closed system where you have to pay for every mod/equivalent via their store The Sims style.
